This invention relates to battery connecter terminals.

, In battery charging stations it is customary to connect batteries for charging by driving steel pins, connected by a conductor w re, into the lead terminals of adjacent batteries. These pins are subject to rapid corrosion which is due in great part to improper connection of the conductor to the pins, thus causing resistance and heating at the connections.

One important object of the present 1nvention is to provide an improved form of pin terminal connecter wherein a poslt ve l5 electrical connection is made between the pins and the conductor so that local resistance due to improper and inefiicient connections is eliminated.

A second important object of the lnvention 2C is the provision of an improved terminal having a plurality of driving points so arranged that they may be selectively used whereby, when one point becomes corroded and useless, another point is available and the life of the terminal is thereby prolonged.

A third important object of the invention is to provide a novel form of terminal 1n such a battery connecter arranged to provide a driving head for a terminal pin or pins.

With the above and other objects in view, the invention consists in general of certain novel details of construction and combinations of parts hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and

Figure 1 is a plan view showing several batteries connected in series by means of connecters constructed in accordance with this invention;

Figure 2 is a plan view of one of the terminals and a portion of the conductor wire;

Figure 3 is a side elevation thereof;

Figure 4 is an end view thereof;

Figure 5 is a section on the line 55 of Figure 3, and showing one method of securing the conductor wire to the pins; 7

Figure 6 is a similar section showing a modified arrangement of the pin and com ductor connection; and I j I Figure 7 is a similar section showing a second modification of this connection.

In the embodiment of the invention, as here illustrated,there is. provided a cruciform head 10 having a boss 11 projecting perpendicular to the. arms from thejunotion of said arms. Projecting from two adjacent arms are pins 12, the arms opposite those from which the pins project being provided with flattened ends 13 to receive hammer blows.

In the form shown in Figure 5,-the pins 12 are made from a single length of steel having a right angle bend centrally of its length. 66 This bend is flattened to provide a disk 14 from which is punched out a loop or strap 15 around and through which extends the ter-. minal portion '16 of an insulated conductor wire 17 The head 10 is formed of an alloy of antimony and lead similar to the well known type metal and is cast around the pins and conductor so that the conductor extends through the boss '11. This makes an eificient electrical connection between the wire and pins and also affords means whereby either pin be driven into a terminal T of a battery B.

In the form shown in Figure 6, the pins 12 are made separately and are connected by a 8 short piece 18 of wire around vwhich is wrapped the terminal portion 16 of the conductor 17 as before.

In the form shown in Figure 7, the pins are made, as in Figure 5, from a single piece 5 of wire but the bend is not flattened, the terminal portion 16 of the conductor being simply wrapped around the bend.

In each of these forms, the portion 16 may, if desired, be soldered in position before the head 10 is cast on the pins and conductor ends. I

The device is used in the ordinary manner, the desired pin being driven into the terminal by blows on the opposite face 13.

There has thus been provided a simple and elficient device of the kind described and for the purpose specified.

It is obvious that changes may be made in the form and construction of the invention without departing from the principles thereof. It is is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as come Within the scope claimed.

Having thus described the invention, what is claimed is 1. A battery connecter including a-terminal having a double pointed pin formed from 10 a single length of wire bent to position the points at right angles to each other,'the bend of the wire being flattened to form a disk and having a loop struck therefrom, a conductor wire having its terminal portions engaged through said loops, and cruciform heads surrounding said pins and having the V pins extending axially outward through two of the arms, the head being provided with a boss through which the conductor extends. 2. Abattery connecterincluding a terminal, having a cruciform head, pins projecting from two adjacent arms in alinement therewith, a wire within the head connecting the two pins, and a conductor wire having its terminal portions wrapped around the pin connecting wires.

3. A battery connecter including a terminal having a double pointed pin formed from a single length of wire bent intermediate its ends to cause the points tolie at right angles to each other, a conductor wire having its ends wrapped around the respective bent portions of the pins, and a cruciform head formed on a respective bend'and having the pin points projecting axially from two of its arms, the opposite arms terminating in blow receiving surfaces.

In testimony whereofI afiix-my signature. 4
